drm/amdgpu/ras: only check bad page for address-based UMC injection
UMC error injection on MI300 series is dispatched by the RAS TA using
the injection method; only the "coherent" methods are address based,
the single-shot/persistent/ac-parity ones ignore the address.
The debugfs control path validated the injection address against the
bad page list for every UMC injection. On uniras (SMU v13+) devices the
address is now validated by the ras_mgr inject handler, so the legacy
debugfs bad page check only runs on the legacy RAS path; other ASICs
keep injecting by address.
In the ras_mgr handler an injection is treated as non address-based only
when userspace passes the U64_MAX sentinel address and the method is a
non-address method. In that case the address is cleared to 0 and the bad
page / range validation is skipped; otherwise the injection address is
validated as before.
